Whereas GFCI retailers supply dependable safety in contrast with normal retailers, they don’t seem to be meant for each kind {of electrical} system. Some gadgets ought to by no means be plugged right into a GFCI, as they may malfunction or journey the circuit unnecessarily, resulting in energy disruptions or unsafe conditions. Under is an inventory of gadgets not fitted to GFCIs.
1. Units with a “excessive inrush” present
Home equipment like fridges, freezers, air conditioner models, and energy instruments require a critical preliminary burst of electrical energy when powered on. Sure, despite the fact that fridges are nearly all the time positioned in kitchens, the counterintuitive fact is that they’ll trigger the GFCI to journey due to the big preliminary surge of present, even when there is no such thing as a precise fault. This is called “nuisance tripping,” and it’s aptly named. Do not threat spoiling a fridge stuffed with meals by plugging it right into a GFCI.
2. Outside gear
Equally, outside gear equivalent to electrical lawnmowers or stress washers ought to ideally be plugged right into a devoted outside outlet. Whereas GFCIs are designed for outside use to cut back shock hazards, high-powered gear could cause the GFCI to journey if it attracts an excessive amount of present at one time.Â

3. Excessive-powered home equipment
Home equipment that use vital energy, equivalent to area heaters, microwave ovens, or vacuum cleaners, could cause a GFCI outlet to journey, particularly if they’re used on a circuit with excessive masses. These home equipment may create a scenario the place the GFCI journeys incessantly (extra nuisance tripping).
4. Surge protectors or energy strips
Some energy strips and surge protectors, significantly these with a number of plugs for high-powered gadgets, may trigger the GFCI outlet to journey as a result of mixed electrical load. A sudden energy surge or imbalance may trigger the GFCI to journey unexpectedly, defeating the GFCI outlet’s objective and inflicting repeated circuit tripping.
5. Sump pumps
Whereas the National Electrical Code (NEC) particularly mandates that new development contains GFCIs in basements, there’s one other ironic exclusion among the many record: sump pumps. Sump pumps are designed to stop flooding, but when the GFCI journeys and cuts off its energy, your basement would possibly find yourself beneath a number of inches of water.

6. Medical gear
Medical gear like CPAP machines and oxygen concentrators require steady, uninterrupted energy, so we advise plugging these important gadgets into standard retailers, not GFCIs. Some medical gadgets have delicate circuitry, and the GFCI could journey unnecessarily, inflicting a lack of energy to life-sustaining gear.
